INVENTOR WIT/M8358:

mgo b A w I I )W Y citations of securing the separate pieces of;

the Width of the piece 9, and is so located that its lateral face is flush with the lateral face of the piece 9. In assembling the strut, the pieces 9 are caused to overlap, as in the previously described strut, and are so located that the battens 10 are located adjacent to each other in the overlapping portion or joint. Collars 7 are then located along the joint or overlapping portion of the strut, and are secured in place, as has been described, by means of Wedges 8. These collars are so constructed that they hold the lateral faces of'the battens in contact with each other, as Well as forcing one batten in gripping contact with the adjacent piece 9. With this construction the strut is stronger and better enabled to resist lateral bending in both directions. In the first place, each separate piece 9 is strengthened by the batten 10, and the joint is also strengthened, since the battens prevent relative lateral motion between the pieces, and also add to the frictional surface.

This strut, and the one illustrated in Figs. 1 to 3, n ay be readily taken apart or varied in length, by loosening the wedges 8 and removing or shifting the collars 7. The 01 the strut together, and also of dismantling the strut, do not injure or in any way detrimentally atfect the strut, and it ma be used over and over again and be adjust to various lengths, Without in any way injuring it.

What I claim is An adjustable strut, coin rising two separate overla aping pieces 0 equa Width, a longitudinally extending batten of half the width of each piece permanently secured along one lateral edge of each piece so as to form, with the piece, an L-shaped member, the battens being of equal thickness, a series of collars encircling the over-lapping pe tions of the pieces, said collars being of'suoh Width as to hold the adjacent'faces of the battens in engagement with each other, staples for permanently securing the collars in spaced positions on one of said pieces and Wedges cooperating with the collars for fore ing the over-lapping portions of the pieces into gripping engagement with the ad acent portions of the battens.
